122 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Aplopappus pinifolius Gray, Proc. Amor. Acad. viii. 636 (1873). Typo locality, 

 "near Los Angeles [California], in a dry river-bed." 

 On the south slope of the San Bernardino Mountains [No. 123). 



Aplopappus racemosus virgatus Gray, Proc. Amer. Acad. vii. 354 (1868), as 

 A. paniculatus virgatus; Gray, Syn. Fl. ii.pt. i. 127 (1878). Type locality, "Bridge- 

 port [Mono Comity, California], on the eastern side of the Sierra, in alkaline soil." 



At Resting Springs (No. 269). 



Aplopappus whitneyi Gray, Proc. Amer. Acad. vii. 353 (1868). Type locality, 

 "Mono Trail and Sonora Pass [California], in open woods, alt. 9,000 feet." The 

 points are on the crest of the Sierra Nevada westward from Mono Lake. 



Near Farewell Gap, Sierra Nevada (No. 1745). 



Acamptopappus spheerocephalus Gray, PI. Fcndl. 76 (1819), nnder Aplopappus 

 ($ Acampiopappus) ; Gray, Proc. Amer. Acad. viii. 634 (1873). Type locality, 

 "California." 



Not until it began to flower could this shrub be identified, and therefore in the 

 earlier months of the season's work no records of its occurrence were kept. After 

 June 1 it was found near Crystal Spring, Coso Mountains, at Lone Pine (No. 

 890), and southward along the eastern base of the Sierra Nevada to Walker Pass. 

 Again on emerging into the Mohave Desert through Tehachapi Pass we found it 

 continuing westward across Antelope Valley as far as the desert vegetation extended. 

 It is a characteristic shrub of the upper altitudes of the Larrea belt, and is undoubt- 

 edly scattered widely in the desert. 



Bigelovia arborescens Gray, Rot. Mex. Bound. 79 (1859), under Linosyrh; Gray, 

 Proc. Amer. Acad. viii. 640 (1873). Type locality, "California." 



In the valley of the Kawoah River (No. 1753). This is one of the plants that, like 

 Adenostomafascieulatum, are common to the coast ranges and to the western slope of 

 the Sierra Nevada. 



Bigelovia bolanderi Gray, Proc. Amer. Acad. vii. 354 (1868), under Liiwsgris; 

 Gray, Proc. Amer. Acad. viii. 641 (1873). Type locality, " Mono*Pass [California], 

 at 9,000 to 10,000 feet of elevation." 



In the high Sierra Nevada (No. 1690). The leaves of our specimens are much 

 narrower than those of the type, and this, together with the racemose-paniculate 

 inflorescence, suggests a too close relationship with B. parryi of the Kocky Moun- 

 tains. 



Bigelovia graveolens (Nutt.) Gen. ii. 136 (1818), under Chrysocoma; Gray, Proc. 

 Amer. Acad. viii. 614 (1873). Type locality, " on the banks of the Missouri in dentt- 

 dated soils." 



The forms that have heen referred to this species are so badly distinguished, and 

 their types so poorly known, that the reference of* a specimen to any of the varie- 

 ties is very unsatisfactory. It appears likely, too, that Pnrsh's specific name iiaiise- 

 osa must be adopted. No. 652 is a winter specimen of a plant whose leaves drop off 

 early, like those of li. mohavensis, hut it has the whitened stems of B. grareolaix. 



Although this shrub and B. riscidiflora are very generally diffused in the regions 

 of the Sierra Nevada, Rocky Mountains, and Great Basin, no satisfactory account 

 of their distribution in the Death Valley region can be given. The tiowerless state 

 of the different varieties, in which condition only they could be observed during 

 our experience in the desert, did not furnish sufficient diagnostic characters for ac- 

 curate identification. It may ho said in general that B. grareolens was sometimes 

 found at as low an altitude as 900 meters, but usually at a higher altitude, sometimes 

 above the limit of Lan-ea; while li. riscidiflora ranges a little higher. Wherever 

 either species occurred in abundance, the soil was fertile, and responded projitahly 

 to irrigation. Specimens were collected in Surprise Canon, Panamint Mountains
